Drivers face minimum eight-hour road closures as the full impact of the Tour de France on district residents and businesses was finally revealed this week.
Travel through Keighley, Haworth, Silsden, Cross Roads and Oxenhope will be limited to pedestrians and emergency vehicles.
Bradford Council leader Coun David Green warned of “significant disruption” to locals as the 200 riders and their 180-vehicle publicity caravan passes through the Keighley area on July 6.
But he said: “The Grand Depart will be a once-in-a-lifetime opportunity for people to witness the spectacle of one of the world’s greatest events.
“It will bring unprecedented benefits to the district on a truly global scale.”
Coun Green spoke as the council released a package of information to help residents and businesses prepare, along with an initial list of roads on the race route due to close.
The release was cautiously welcomed by some of those responsible for helping meet the challenges of race day.
Steve Seymour, chairman of Keighley Town Centre Association and Airedale Shopping Centre manager, said the package contained “good information”.
But he added: “It’s not what we were promised. It’s not enough to make people aware of how they will get in and out of town.
“I need to know how I can get staff in on race day. We need a detailed map with specific street plans for the town centre.”
Keighley Town Council’s watch and transport committee chairman, Councillor Graham Mitchell, said the information would be useful to the general public.
But he added: “Those of us who have been going to meetings have been piecing together this information. It’s official confirmation of what we’ve been led to believe.”
Roads “on or connected” to the route are expected be closed from very early in the morning for a minimum of eight hours.
They will remain shut after the cyclists pass to give time for crowds to disperse and race infrastructure to be removed.
The council statement said: “Certain roads may need to close earlier and remain closed for longer.
“Routes will need to be clear of all public vehicles prior to the road closure time, with pedestrian access available while the roads are closed.
“Movement of traffic through Keighley, Silsden, Cross Roads, Haworth and Oxenhope will not be permitted.”
Wherever feasible, access will be maintained on key routes across the closed roads.
Detailed information about road closures will be sent to residents and businesses in properties along the route.
Emergency services and health and social care providers plan to maintain essential support. Revised bus and train timetables will be in operation.
The council this week launched a new area of its website – bradford.gov.uk/tourdefrance – to contain all its tour-related information.
